Steering problems on 2005 Ford F-250 Super Duty

steering sticks off and on at all speeds

Asked by for the 2005 Ford F-250 Super Duty
The F250 has a steering box type steering system. It is possible that something is binding up in the steering or suspension but it would be more likely the power steering pump is not supplying sufficient constant pressure. There is a bulletin from Ford about replacing a pressure hose to eliminate a groaning sound from the steering but nothing more specific to your problem. Ensure the fluid level is OK and have it checked out as it may be a sign of something that may become very serious.
